A 8 kg block is hanging from a 5 kg moving pulley. The system starts from rest at State 1. Between State 1 and State 2 a constant 100 N force is applied to the end of the cable. What is the speed of the block after it has moved up by 0.8 m? Ignore friction in the system, the mass of the cable, and the mass of the small stationary pulley (but don't ignore the mass and size of the large moving pulley or the block). State 1 State 2 v1 = 0
